Recent years, various percutaneous procedures including cervical nucleoplasty have been developed for disc decompressions to relieve radicular pains caused by disc herniations. We report the application of percutaneous cervical nucleoplasty (PCN) by using the navigable disc decompression device in two patients of cervical herniated intervertebral discs (HIVD). A 38-year-old female diagnosed wit...

Lumbar disc herniation is one of the most common spinal degenerative disorders which may lead to low back pain (LBP) and radicular leg pain. However, it remains difficult to diagnose a degenerative herniated disc as the LBP generator in clinical practice. The purpose of this study is to explore the characteristic changes of a herniated disc causing LBP on MRI and to clarify the underlying role ...

Percutaneous disc surgery, also known as percutaneous discectomy (PD), for herniated nucleus pulposus (HNP) was introduced by Hijikata [1] in Japan. Indeed, as compared with traditional disc surgery such as love’s procedure, PD is minimally invasive since it can be performed under local anesthesia. However, Hijikata’s technique does not use a spinal endoscope; thus, its reliability for the remo...

Horner syndrome (HS) occurs when there is interruption of the oculosympathetic pathway. The causes of HS are various, but HS originated from herniated cervical disc is very few. HS attributable to the lesion of the first-order neuron of cervical spinal cord is extremely rare. A 41-year old male was admitted for sudden onset of left ptosis and right side numbness. Neurological examination reveal...

Microsurgery for lumbar herniated discs that require surgical intervention is a very successful and well-described technique, whether performed through more traditional "open" microsurgical retractors or through minimally-invasive "tube" retractors. Surgery for extruded lumbar disc fragments that migrate caudad or cephalad from the disc origin may typically require modifying the standard hemila...

STUDY DESIGN A case report. OBJECTIVE To demonstrate a case of intradural lumbar disc herniation including imaging studies, intraoperative imaging, and an intraoperative video. SUMMARY OF BACKGROUND DATA The first case of lumbar intradural disc herniation was reported as early as 1942; since then more than 150 cases have been reported, mostly in the lumbar spine. Gadolinium-enhanced magneti...

The aim of the present study was to compare the relationship of morphologically defined non-bulging/herniated, bulging and herniated intervertebral lumbar discs with quantitative apparent diffusion coefficient (ADC). Thirty-two healthy volunteers and 28 patients with back pain or sciatica were examined by MRI. All intervertebral lumbar discs from L1 to S1 were classified according to morphologi...

BACKGROUND CONTEXT The optimal surgical treatment of thoracic disc herniations remains controversial and depends on the consistency of the herniation and its location related to the spinal cord. PURPOSE To compare the outcomes of patients with symptomatic thoracic disc herniations treated with anterolateral mini-transthoracic approach (TTA) versus posterior transpedicular discectomy. STUDY ...

Intervertebral disc herniation of the lumbar spine is a common disease presenting with low back pain and involving nerve root radiculopathy. Some neurological symptoms in the majority of patients frequently improve after a period of conservative treatment. This has been regarded as the result of a decrease of pressure exerted from the herniated disc on neighboring neurostructures and a gradual ...
